Simulation of paste extrusion requires knowledge the material–wall interactions and bulk deformation behaviour. A systematic approach to decoupling these is presented for a stiff paste, comprising microcrystalline cellulose/calcium carbonate/water, employing three different experimental configurations separate paste-wall friction from rheology. The yielding behaviour was identified ram testing ...
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
Zusammenfassung. Bei der Untersuchung von Muskelbiopsien sind zur diagnostischen Präzisierung meistens morphometrische Analysen notwendig. Die lichtmikroskopischen Aufnahmen von gefärbten Semidünnschnittpräparaten von Muskelbiopsien werden dazu in kontrastoptimierte Graustufenbilder transformiert. Nach der Kantendetektion mit einem hierarchischen CannyOperator folgt die Verkettung der gefundene...
unter den verschiedenen bereichen der komparatistik begegnet man einer der in letzten jahren entstandenen disziplinen, die sich gezielt und orientiert bezüglich der historischen und kulturellen quellen versucht, die literarischen relationen zwischen den verschiedenen sprachen durch analyse der fremden episoden zu erl?utern. die imagologie ist ein zwischenkulturelles wissen, das den anderen wiss...
Does a protein on the surface of some of our cells explain why certain people are more at risk from covid-19? The coronavirus attaches to a receptor protein on the surface(ACE) of our cells to gain entry to them. The protein is carried by cells in the nose, lungs and gut. It is possible that variation in how much of this protein people have may help explain why some are more likely to die from ...
Since tubes have numerous industrial applications, different attempts are focused on the Severe Plastic Deformation (SPD) processes of tubes. As an illustration, Tube Channel Pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of greater s...
diese wissenschaftliche arbeit, die als magisterarbeit für das studienfach „didaktik der deutschen sprache“ geschrieben wurde, befasst sich mit der novelle „der tod in venedig“ von dem berühmten deutschen schriftsteller „thomas mann“. nach kurzer vorstellung der biografie von thomas mann und der zusammenfassung und der interpretation der novelle wurde zun?chst kurze die ubersetzungstheorie und...
in the present work, the effects of changing punch and the die radius on several process parameters involved in deep drawing of aisi 304 steel have been studied. deep drawing process of a cylindrical cup was simulated and analysed by numerical modeling. the results were compared with those of obtained from a serie of experimental cupping tests. the comparison shows that: maximum drawing force d...

The effects of input parameters on the square-cup deep-drawing process for a two-layer aluminum/steel laminated sheet were investigated. Each layer was 0.7 mm thick, and the input parameters covered in the investigation were punch nose radius (PR), die shoulder radius (DR), the clearance between a punch and die (CPD), blank holder force (BHF), and layer arrangement (LA). The effects of the inpu...
